If you’re working in Terminal on your Mac, you need to know the most important UNIX commands: those that work with directories, those that work with files, and miscellaneous but commonly used commands. Folders are called directories in UNIX. Commands that refer to filenames, as most do, assume that you’re talking about files in the. Just like Windows, Mac also comes with its own command prompt line interface, Terminal application (Unix commands). Learning about the Terminal app could come in handy and will help you go deep in Mac OS settings with ease. Not only this, there are other reasons too.
Folders are called directories in UNIX. Commands that refer to filenames, as most do, assume that you’re talking about files in the working directory. When you open the Terminal window, the working directory is set to your home directory, abbreviated ~. Bash shows you the current working directory and your username to the left of its prompt. The following table lists common directory-related commands.
| Command | What It Does |
|---|---|
| ls | Lists the names of the files in the working directory. For more complete information, use ls –alF (. |
| cd directoryname | Changes the working directory to the one you named. |
| cd .. | Brings you up one directory level. |
| cd | Returns you to your home directory. |
| pwd | Displays the pathname of the current directory. |
| mkdir newdirectoryname | Makes a new directory. |
| rmdir directoryname | Removes (deletes) an empty directory. |
As in Windows, you can redirect the output of a command to a text file. So if you want a record of the files in a folder, type cd, followed by a space, drag the folder’s icon to the Terminal window, and press Return. Type ls > mydirectorylist.txt and press Return again. A file named mydirectorylist.txt will appear in the folder you chose. You can open the file in TextEdit to see a list of the files in that directory.

| ps | Displays a list of running processes. |

When you’re working in Terminal, you don’t have a Trash Can to which deleted files are moved pending ultimate disposal. Delete it, and it’s gone. In general, UNIX has no Undo function.
